If you were 4 and now you are 44 then you might be an integer variable. If sister is also a variable, we don’t know when she was allocated. She might also be an integer constant in which case she’s arguably immortal.

If your parents had another daughter in the meantime (or if your older brother became female), “my sister” would still be a valid reference, to a completely different person.

D can also happen if the 00:45 job was before the 00:15 job, which thanks to the magic of daylight savings, is also possible

I have a taxi company. On one night, one of my drivers did two jobs, one dispatched at 00:15, the other at 00:45, and he clocked off at 02:15. How long was he working for?

A) 1 hour

B) 2 hours

C) 3 hours

D) 2 hours 30 minutes

E) any of the above

At all levels too. I mean, why the 24 hours a day fluorescent lights so you don’t know night from day? How does that help? Hell, how does it even make more money? Even with senior management, the cruelty is the point.
